Guinea-Bissau Sign Language
Guinea-Bissau Sign Language是一种手语，主要分布在几内亚比绍。
手语是完整的自然语言，有自己的语法；它们与当地口语并不同源。
Guinea-Bissau Sign Language (Portuguese: Língua gestual guineense or Língua de sinais guineense) is an incipient sign language evolving from the single school for the deaf in Guinea-Bissau, which was founded in Bissau in 2003. In 2005 a linguist and Portuguese Sign Language teacher found GBSL to still be basic, but with some consistency among students in the school and village use when the students went home.
It is not directly related to the Portuguese sign language, although it has borrowed the alphabet from it.
